Changing password for FRITZ!Powerline network

FRITZ!Powerline allows you to expand your home network using the home's own electrical wiring. To do so, simply connect two or more powerline adapters to form a powerline network. The connection between the FRITZ!Powerline adapters is encrypted with a network password (AES 128-bit), thus protecting it from unauthorized users. Each FRITZ!Powerline adapter has its own network password upon delivery. You can also assign a password of your choice to FRITZ!Powerline adapters; however, the same password must be assigned to all adapters within a powerline network.
